Each species is separated by a vertical bar, with the species in each half-cell grouped together, and the two half-cells separated by two bars or slashes representing a salt bridge (which generally contains an electrolyte solution such as potassium nitrate or sodium chloride that is left unwritten).
Cell notation may be used to represent other information that is not essential to the reaction but still useful to include.
The standard abbreviations for the phases of each species are often included as subscripts, in a manner similar to the notation in chemical equations.
Both of the electrodes are immersed into aqueous media where zinc and chloride ions are present.
For example, in the Galvanic cell: In this case, all ions (sulfate, zinc and copper) are in a concentration equal to 1 mol/L.
